Alloy Stainless Steel Aluminium Cast Iron Tool Steel * Parameters shown are only starting points. Speed should be calculated using the drill diameter. Due to the short drill distance required, speed and feed rates can possibly be elevated. Coolant through the cutter is preferred. Flood, Mist or Air coolant can also be used. No spot drilling, pre-drilling, or dwell required.
